A screw threadedbar 33, connected to one end of the link 32 and passed through a lug 34secured to the base i3, is provided to move the -1ink '32 to swing thearms 3i and rotate the cylinders 28 and. 29. The bar 33 may be moved bymeans of nuts 35 and 3t screw threaded on the bar 33, one at'each sideof the lug '34;

A bar 31. carried by, and on each of the stud shafts 26and 27, has eachof its ends connected to one of a pair of plates- 38 and 39 throughblocks ll. The plank supporting members 14, adjacent the eccentricallymounted sprockets 2|, are respectively secured to the plates 38 and 39by screws 42, the plate 38 connecting together all of thesupportingmembers l4 atone sideof 'the groove 11, and the plate 39connecting together all of the supporting members M at the other side ofthe groove 11. By this arrangement, the rotation of thecylinders28-and'29 will move the members I 4 connected to the plates 38 and 39simultaneously With any adjustment of the eccentrically mountedsprockets 2 1. As more clearly shown in Figure 4, the joint between the-movable supporting members, M is formed by overlapping their ends, asat 43, with the adjacent ends of thestationary ones whereby the sides ofthe grooves l5 and I7 between these members will not be interrupted. Y

The mechanism herein shown for applying ink I to the plates H as theyare moved by the chain 4019, includes two cooperating fountain rollers5| and 52, and aplate inkingroller 53 "(see Figures 1, 2, 5 and B). Theshaft ends'fifi and 55 of the fountain rollers "5| and 52 respectively,are journaled in spaced apart uprights *5'6 and 51, se- 5cured to theframe [3 by bolts Bil. 'Thefountain rollers -5lf'and 52 cooperate bybeing adapted to engage at their opposing faces to form a troughtherebetween to hold ink and to act as an ink mill.v The troughformedbetweenthe rollers 5| and 52 is closed at each end by aV-shapedplate 58 which fitsthe adjacent peripheral portion of eachroller and is spring pressed thereupon by a spring 59, which springreacts between the upper edge of the plate 58and a sleeve 6iscrew-thread- 'ed in a lug 62 formed on,- or securedto, each upright 56and 51. The sleeve BI is provided with a handwheel 63 by which it may berotated to adjust the tension of the spring 59. A rod '64 threaded'intothe top of each of the'V-shaped I plates extends upwardly through eachsleeve 6! to above the hand. wheel 63. The rod 64 is engaged-by a nut 65whereby engagement pressure ofthe plate 58upon the rollers 51 and52may-be *varied. i

The rollers El and 52 are power driven from I the chain driving motor 22through a chain 8i led about a sprocket 82 secured on the shaft 25 andwhich extends to and is led about a sprocket 83 on a-vertical shaft 8 5journaled in the base IS.

The shaft 84 has a bevel gear 85 keyed to its upperend which meshes witha bevel gear 86 keyed to one shaftend 5d of the roller ii. A spur gearis preferable that the roller 5'! be driven slightly *slower than theroller '52. Both sets of bevel gears 85 and 86 and the spur gears 31 andstare preferably enclosed in oil-tight housings 89. and

The inking .roller53 has each of its shaft-ends 92 journaled in abushing 93, the outer periphcry of which is' eccentric to theaxisof theroller 53. Each bushing 93 is clamped in an arm ill of a'leveriifi by acap member 96, .swingably connected by links 9 7 to the arm fillandadapted to be "tightened against the bushing '93 by a clamp A 88. -Eachlever 55 is mounted on a stud 99eX- tending from one of the uprights "56and 5?. Another arm 'llll of the lever is acted upon by a spring I 52which reacts between a stud H33 screw threadedinto the arm NH, and a lug1&4 extending outwardly from each :upright .55 and 51. Rotation'o'f 'thestud 33 varies the tension of the spring M2. The springs i262 constantlyact upon the levers 95 to press the roller L53 against the roller 5iwhereby it will receive ink therefrom to transfer it to the plate l'i. Aset screw I65 is threaded through alug lite extending from-the armfi lto engage a lug till provided on the adjacent upright '55 or '5? tolimit the pressure of the roller 53 against the rollertl.

The frame members2l4 and H5 are each slidably mounted upon.a pair of spaced apart posts 2116 and 2H, which in turn are s'lidablydisposed in holes 218 provided therefor in'the base of the framel'3. Theposts 256 and 2!! are formed to provide a portion 221, smaller'indiameter where they pass through the frame members 2 l4 and 215 thanwhere they pass through the base frame l3, to provide an upwardlydirected shoulder 222 upon which the frame members 2M and M5 may seat. Acoiled counterweight spring 1223, of sufficient tension to support itsportion-of the weight of the frame members2l4 and H5 and the cylinder 2|I, with their associated parts is disposed about each p stZI-B and 2H,and reacts between the ad- ;jaceiit frame member 214 and 215 and thebase frame l3.

Th lower end of each post 2H6 and .211 is "threaded and has aninternally threaded wormwheel 22 4 operatively mounted thereon. Theworrnwheels 224 engage a bracket 225 seated against the-undersurface ofthe base frame I3 '"and are thereby adapted to draw the posts 215 'a nd2l1 downwardly against the tension of the counterweight springs, and toadjust the position of the shoulder 222 to limit the downward "movementof the frame members 2I4'and 2| 5 and the'oylinder2l I. A shaft 226having a worm gear 221 thereondisposed between thewormwheels 224 onadjacent posts 2l6 and 2l1, has a hand wheel 2.28 (Figure 2) securedupon one of its outer. ends. whereby all four wormwheels 224 may besimultaneously rotated.

' A pressure spring 229 is provided, coiled about the'upper end of eachpost H6 and 2H to react betweenthe adjacent frame member 2-l4'or2-l5,and abracket 23l extendingbetween the posts in each frame member 2I4andf2i5, to press the frame members downwardly toward the shoulde'rs222and maintain a desired pressure of the cylinder '2 against the plate Has it passes under the cylinder. A wormwheel 232 is screw threaded uponthe upper end of each post 216 land 211 and engages the adjacent bracket23L Simultaneous rotation of all of the four wormwheels 232 is obtainedby means of a shaft 233 having a pair, of worm gears 234 thereon, eachpositioned (asshown inFigure 1), to mesh with two-of the wormwheels onthe posts in each of the frame members 2M and 215,. The shaft 233 thepressure of the cylinder 2 on the, plate H.

In order to adjust the elevation of the ,bearings for each end of theicylinder 2H separately, one of the worm gears .221 is preferablyprovided with a suitable locking device :not shown, where'- .by it maybe locked to the shaft 226 in any desired angularrelation, andsimilarly, one of the worm gears 234 may be adjustable withrelation tothe shaft 233 so that the impression pressure at each end of thecylinder 2i I may be separately adjusted.

. A bar 236 extends between the frame members 2M and 2 I 5 and anotherbar 231 extends between the brackets 23! 1 adjacent each of the framemembers 2M and i2l5. The bars'236andr231are parallel and are spacedapart, and the upper one 231 has a pressure indicator 238 mountedthereon adapted to be actuated by a pin :39 mounted di- .rectly below iton the bar 236, whereby the pressure of the cylinder 2H upon the plate Hwill be. indicated.

Plank back-up rollers 241 and 242 are provided and arerotatablymountedupon bushings 243 which are in turn mounted upon .a stationary shaft244. The shaft 244 is secured to and is carried "in eccentric bushings245 and 246 which in turn are rotatively mounted in the base frame 13.Rotationof' the shaft 244, due to its mounting in the eccentric bushings245 and 24.6, as above described, will adjust the back-up pressure ofthe rollers 24! and 242 upon the plank l2.

The cylinder 2: is arranged to be rotated by the chain driving motor 22(see Figures 1 and 10') from the gear 288 on the cam shaft 203 through agear 241 in mesh with the gear 258 and secured on a vertical shaft 248,a bevel gear 251 slidably secured on the shaft 248 by a key 249, and abevel gear 252, adapted to be detachably connected to the shaft end 212of the cylinder 2H and which is constantly in mesh with the bevel gear25L The means to detachably connect the bevel gear 252 to the shaft end2|2 includes. (see Figures 11 and 12) a plate 253 securedto the shaftend M2 by screws 254. A cylindrical boss 255 extends axially from theplate 253 andis provided with a bore 255 in which one end 251 of a shiftrod 258 slidably entersl The shift rod end 251 carries a cross pin 259which extends through the boss 255 in an axially I elongated slot 261provided therein whereby its ends may seat in segmental recesses 262formed in the rear face of a hub portion 263 1 formed on the bevel gear252.

A coiled spring 264, reacting between the shift rod end 251 and thebottom of a hole 265 formed in the shaft end 2|2, is provided toconstantly urge the ends of the cross-pin into the recesses moved todisenga e the ends of the pin 259 from the recesses 262 by beingprovided with an annular recess 2.61 in its outer end in which a stud25.3 rides. The stud .268 is eccentrically disposed .on the end'ofashaft .269. The shaft .269 extends through a gear-enclosing andoil-tight casing 21] and has an operating handle 212 secured thereto.outside-of thecasing .21] (see Figures 1 and 2) by whichit may berotated to shift the rod 258. The bevel gear 252 :-is rotatablymounted-upon a sleeve 21 3 which extends from the cylindrical vboss.255. The :sleeve 213 extends along the rod 258 beyond the gear 252 andthrough a brake shoe 216 and a stationary brakeplate 211. The brakeplate 211'is fastened by bolts 218 to a cover 219 for the casing 211,and the brake shoe 256 is keyed to the sleeve 213 by :a key 281 whichseats in an elongated slot 282 formed in the sleeve .21,3. A; spring 283coiled about the sleeve 213 reacts between the brake shoe 218 and acollar 1284 abutting the gear 5252 to prevent rotation of the cylinder 2when the pin .259 is disengaged from the vgear 252, by manipulation ofthe han- Idle .212, and .at other times presses the pin .259
